My understanding is the car has a hot V. Ie the turbos are inside the V of the engine. The engine as far as I understand, does away with a normal intake manifold (which are mostly plastic these days). Hot V engines are not new. F1 has been using them since 2014. Major manufacturers bmw, audi and Mercedes use them. Increasing the water jacket size is normal to dissipate thermal load caused by 830hp. The 296 creates a huge amount of heat with its hybrid pack, but if you carefully watch the engine thermometer you will see that the temperature is controlled very very well even in 30deg+ temperatures. I have had a 296 GTB and GTS and have not suffered any issues to do with the car dying out (yet!). I did get an issue on my GTB when I started it after 3 hours of use (and 2 hours sitting) where a plethora of lights came on( but I was seriously low on fuel). I had the engine light come on, a misfire and lots of warnings (no hybrid or battery warning’s). I put it down to being very low on fuel. It was fine after refuelling. I personally think Ferrari has done an epic job and has really pushed the envelope. They have done an excellent job on the engineering side. You will always have issues with electric systems for hybrid cars in their nascent form. You must remember, Ferraris are made in very low numbers and as such any issues will show up more readily. I have owned Ferraris for 18 years and I think they have done an incredible job with the 296. I just think the styling is a bit soft !!!
